Expansion Teams Plan Tournament

The Orlando Magic and the three other expansion teams will announce on Thursday that that they will play a preseason tournament next fall at the Charlotte Coliseum.

A source familiar with the agreement said the Magic, Minnesota Timberwolves, Miami Heat and Charlotte Hornets will play doubleheaders on successive nights, with the winners on the first night meeting for an ''expansion championship'' the next night.

The dates for the event have not been announced. The general managers of all four expansion teams, including Pat Williams of the Magic, are scheduled to attend Thursday's announcement in Charlotte.
